With the exception of the cap (which is usually part of a good preflight
on GA aircraft), the rest are fuel system failures, not "running out of
gas".

Breaking his post down into the following items:

Fuel cell/bladder/tank leak in flight,
fuel cap improperly secured and is blown away in
flight resulting in siphoning of fuel,
ruptured fuel line,
clogged fuel filter,
fuel pump failure, etc., etc, etc.

I see five items, three of which *definitely* fall into the category of
"running out of gas" (in that they all can lead to fuel exhaustion in
addition to the possibility of fuel starvation), and a fourth (fuel pump
failure) easily could fall into that category as well (depending on the
nature of the failure...any failure where fuel leaks from the pump can
result in fuel exhaustion...that is, "running out of gas").

A "fuel system failure" is not mutually exclusive with "running out of gas",
and that was (I think) Peter's point in the first place.

It's certainly true that most engine failures are caused by "running out of
gas" and most instances of "running out of gas" are simply due to pilot
failure. But to say that that's true 100% of the time is simply wrong.
